we are developing compounds that can help reduce energy consumption due to lower friction or wear, or by creating materials with a longer service life. When possible, we will also use recycled materials or additives in our compounds.” Specialty metal sulphides producer

Tribotecc provides solutions for a wide range of applications including friction, lubrication, powder metallurgy, electronics and the polymer industries. “In polymers, these functional additives are used as solid lubricants in technical and high-engineered thermoplastic compounds such as PA, PPA, POM, PEEK and PTFE, as well as thermoplastic elasto- mers, to improve tribological properties such as wear and the coefficient of friction,” says Ing Clemens Kappl, Head of Market & Technologies. “We offer a wide range of customised synthetic solutions supported by reliable test data from our tribological competence centre in Austria…We are also listed as a lead registrant under REACH for various substances like tin, bismuth, tungsten and copper sulphides, for example,” he says. “In addition, Tribotecc has developed several new
synthetic, light-coloured and lightweight metal sulphide systems as alternatives to existing graphites, molybdenum disulphides and silicon oils, which offer better wear and micro-perfor- mance for modern polymer compounds. These solid lubricants can also be offered in granulated form as well for easy and dust-free handling.”
Lightweight challenge The company says that lightweighting with poly- mers is becoming increasingly challenging for the development of highly stressed components in motion, such as gear wheels, bearings, values and pumps. “To fulfil these requirements for the automotive industry, it is necessary to understand material science and functionality of polymer systems,” according to Kappl. “We envisage using our expertise in this area to provide solutions in the future for plastics in sustainability, e-mobility and digitalisation, for example.” Italian compounder Lati has developed a POM-based compound that is formulated to offer good tribological and mechanical features, as well as excellent resistance to solar radiation. The compound is being supplied to GGB for its EP15
